項目簡介

太空中探測到的170個分子中,大部分分子是在Orion KL和銀心Sgr B2(N)和(M)大質量恆星形成區探測到的。Orion KL區域包含熱核、緻密脊、環境低溫成份,Sgr B2(N)區域有大量的有機分子,Sgr B2(M)是銀河系最亮的紅外源。這些區域包含了大質量恆星形成過程中豐富的物理和化學過程。本項目將利用太空望遠鏡Herschel/HIFI譜線巡天資料以及地面設備對這三個區域進行分子天體化學研究。用地面望遠鏡觀測得出所研究分子的氣體分布、溫度和密度結構,然後用這些物理量對Herschel/HIFI資料進行模型擬合,對所研究的化學成份求得精確的物理參量。於是這個研究的主要目標是:1,確定有機分子在不同環境的化學路徑,即這些分子起源於塵埃顆粒表面,或高溫氣相的第二代分子;2,用簡單分子吸收線,研究銀河系彌散源雲化學;3,用分子躍遷測量銀心區的元素同位比,探討銀心區重元素核合成問題。
